The problem is that gprbuild (which Pascal was using) can be very
misleading about the command lines it actually issues.

So when Pascal said

$ gprbuild -P acr.gpr -aP /usr/local/xnadalib-2016/share/gpr
gcc -c fileio.adb
fileio.adb:529:16: warning: index for "ext" may assume lower bound of 1
fileio.adb:529:16: warning: suggested replacement: "ext'First"
fileio.adb:529:42: warning: index for "ext" may assume lower bound of 1
fileio.adb:529:42: warning: suggested replacement: "ext'First"
gcc -c sets.adb
gprbind cr.bexch
gnatbind cr.ali
gcc -c b__cr.adb
gcc cr.o -o acr

all those lines are just a hint of what was actually going on; you need
to call gprbuild to manage the process.
